Timelineplot generates simple line plots from two columns of character-delimited data. The first column represents the time variable (x-axis) and the second column contains the values to be plotted.
Timelineplot is a wrapper for gnuplot with many options in the plot script adjustable by optional command line arguments.
timelineplot <datafile> <imagefile> [options]
When the data file is -, data is read from standard input.
The most immediately useful command line options are -sep and -tfmt which set the column separator and time format used in the input data file.
For adjusting output, the -h, -w, and -xfmt options set the image height, width, and the format string for x-axis tic labels.
See the manual for the full list of options.
A very basic example without any of the optional arguments:
timelineplot jan1-2.txt 1.png(Also equivalent would be timelineplot - 1.png < jan1-2.txt and cat jan1-2.txt | timelineplot - 1.png.)
Use a time formatter for the x-axis tic labels and make it wider:
timelineplot jan1-2.txt 2.png -xfmt "%l %p" -w 600
Use just about all the options at once:
timelineplot jan1-2.txt 3.png -h 432 -w 543 -xfmt "%l:%M %p" -title "Temperature" -linetitle "I'm a label!" -xlabel "Time" -ylabel "Fahrenheit" -ymin 70 -ymax 100 -xmin "2019-01-01 06:30:00" -xmax "2019-01-01 08:30:00" -xrot 20 -lc "red" -bgcolor "#ccff99" -grid ytics -font "courier" -fontsize 14 -fontcolor "#8800ff"
